<h3><u>Question:</u></h3>
The rectangle below has an Área of x^2 + 11x + 28 square meters and a length of x+7 meters. What expression represents the width of the rectangle?
<h3><u>Answer:</u></h3>
The expression representing width of rectangle is (x + 4) meters
<h3><u>Solution:</u></h3>
Given that rectangle has an area x^2 + 11x + 28 square meters and a length of x + 7 meters
To find: width of the rectangle
<em><u>The area of rectangle is given as:</u></em>

Here area = x^2 + 11x + 28 square meters
length = x + 7 meters
<em><u>Substituting the values in given formula,</u></em>

Cancelling (x + 7) on numerator and denominator,

Thus expression representing width of rectangle is (x + 4) meters
